Both are invalid - sure it needs to be fast - which is why they should practice this. Temporary means they plan to pick it up after practice. They should do yearly drills in different parts of the world (obviously with permission of the host country) just to prove they can.
Exactly. Either you can tear it down before the storm hits (good weather prediction needed) then rebuild it fast afterwards; or you build it to withstand storms. I guess there is the just scrap it after every storm - but then you need to rebuild it fast and cheap which this wasn’t.
